6.5 weeks pregnant. i know its normal to have to use bathroom a lot but is it normal that i don't have a lot of urine even though i gotta pee real bad?

Not normal: Push a lot of water, at least 100 ounces today and get into your physician to be tested- you may have a bladder infection.

Rule out infection: You may have a urinalysis tract infection. Have your doctor evaluate you. You should drink plenty of water. At least 8 glasses per day. Also sometimes depending on the position of your uterus. As it grows it may be putting pressure on the neck of the bladder causing a slight obstruction . In any case you should be examined by your gynecologist for proper diagnosis.
